+--window=[N], --depth=[N]::
+ These two options affects how the objects contained in the pack are
+ stored using delta compression. The objects are first internally
+ sorted by type, size and optionally names and compared against the
+ other objects within `--window` to see if using delta compression saves
+ space. `--depth` limits the maximum delta depth; making it too deep
+ affects the performance on the unpacker side, because delta data needs
+ to be applied that many times to get to the necessary object.
